The name for your corporation always has to end in a “legal element”. A legal element is the “Ltd.”, “Limited”, “Inc.”, “Incorporated”, “Corp.”, or “Corporation” that goes at the end of the name.
What’s the difference between those six things? Nothing – they all mean the same thing in Alberta. Pick whichever one you think sounds best with your name.
There are terms that mean something different (e.g., ULC or LLP) that mean something different, but there is no difference between Ltd./Limited, Inc./Incorporated, and Corp./Corporation.
